I agree and stand corrected. The powders listed are not one's I've ever used and I didn't have it in front of me when I posted. I remembered that I thought it was useless.

It would have been more correct to say that the powders listed are limited and, in my experience, not common. I'm biased in that I've been disappointed by the Barnes Manual all along.

Certainly is a lot of "passion" here over the .458! That's a good thing! It helps keep our sport alive.

I have a CZ in .458 Win., and as CZ550 noted, the throat is unusually long in those rifles, allowing the handloader to seat bullets farther out. That pretty much eliminates the compression issue. Mine loves 72 grns. of H4895 under the 450 grn. TSX. This load gives me a consistent 2225 fps., and 1 1/2" groups at 100 yds., and shoots to the same point of impact whether it's 100 degrees or 15 below. While I have never killed an animal with this rifle, my common sense leads me to believe this load would be up for any challenge that presented itself, and I would be confident in it.

Keep the passion guys! I've enjoyed the read!
